Survival Curves for Stage IV melanoma

This is a composite of data from 42 phase 2 clinical trials in patients with Stage IV melanoma.  It was published to be used as a benchmark for determining whether studies should advance to a phase 3 setting.  As you can see, when you take the 0.5 point, and move it over to the curve, median point of death is around 6-7 months.  Cheery, huh????
